Thank you very much, Roland
Your response is very insightful and gives practical insight.
I have attached below screengrabs of my project with the Timeline, Branch Precomp, and Title Precomp; I will refer to these.
I’m learning to crawl before I can walk, so I’ve structured the composition/project so that expressions can manipulate it.
The branches and titles for the mindmap animation/motion graphic have been precomped separately to keep order and simplify control. In the Branch Precomp, the layer has been duplicated and narrowed down to a single path in the previous order so that it can be implemented simply by sliding 0 to 100. The Title Precomp has every title and icon masked out and separated so that the Branch Precomp layers can trigger each layer.
Before, I would copy and paste keyframes within the branch and title layers to maintain consistency, yet this manual process proved time-consuming and high-risk.
Now that manual and automation are merging, I have added markers to the VO layer in Audition so that its paced KFs will trigger each of the branch layers’ stroke generation effect within the branch pre-comp.
Is this updated procedure in line with what you advised and possible within the limited knowledge of AE coding?
